Nickname for a grandparent?

.... Josh's mother wants to be Mom-Mom but I have issues with that and just call her 'your grandmother' to Aidan. Josh's father is Pappy.

she was already someones' mom, and josh needs to be the one to tell her YOU are the only mom. IMHO

My niece calls my mom and dad, Mamaw and Papaw.

My dads dad and step mother are referred to by my sister and I, and now Eden (niece) as Grandpa Joe, and Grandma Mary.

My mom's mom (deceased) was Mamaw Verne. Her name was LaVerne. I sure do miss her.. I never met my moms dad, he passed away when she was 13. My older cousin, my aunts son, first started calling her that because Mamaw Verne's mother was Mamaw, and instead of calling them both just Mamaw, she was referred to that way.

My dad's real mom and step dad were MawMaw, and PawPaw.
